Winsor & Newton's Series 7 Kolinsky Sable Brushes are made from only the finest Kolinsky Sable hair in rust-proof, seamless nickel plated ferrules with black polished handles. Series 7 brushes are still hand-made in England by Winsor & Newtons expert brush makers, each with over 10 years experience. The standards of quality for this brush were set in 1866, when Her Majesty Queen Victoria gave orders that Winsor & Newton should produce the very finest water color brushes in her favorite size, the No.7.
